We follow the test signals considered by [1]} and then by [2]} which involves 5 different formats of signals with length from \(n=140\)  to 2048: (1) blocks, (2) fms, (3) mix, (4) teeth10 and (5) stairs10. The specific settings of these signals including the sample sizes and noise standard deviations are given in Appendix B of [1]}. Following the experiments done in [2]}, we also consider an additional signal setting by changing the standard deviation of (2) fms from 0.3 into 0.2, which is also one of the settings studied in [5]}. An example of one profile of the simulated data and the underlying signals \({\gamma }^{*}\)  are plotted in Figure REF . For each signal, the experiment has been replicated 1000 times. The results are shown in Table REF . The performance of each estimator is stated as follows.
